SPECIFICATION forming part of Letters Patent No. 736,822, dated August18, 1903. Application filed November 24, 1902. serial No. 132,668.' N3151mie1- Y .To aZZ whomV t may concern;

Beit known that I, DAVID RUDOLPH. COT- NER, a citizen of the UnitedStates, residing at Bardwell, in the countyV of Carlisle and State ofKentucky, have invented certain new and useful Improvements in Chairs;and I do declare the following to be a full, clear, and exactdescription of the invention, such as willenable others skilled in theart to which it appertains to make anduse the same.l

My invention relates to a duplex rockingcliair in which thereciprocating motion is imparted by pressure on the footboard, and isdesigned to take the place of the derrickswings used upon porches,verandas, and lawns.

The object of the invention is to produce a chair of this characterwhich will have an easy and almost level reciprocating motion, similarto a swing, without the use of the supporting derrick or frame, which iscomposed of few parts, detachably connected and designed to be compactlyfolded for transportation, and which is simple in construction, durablein use, attractive in design, and comparatively inexpensive ofproduct-ion.

With the above and other objects in View, which will readily appear asthe nature of the invention is better understood, said inventionconsists in certain novel features of construction and combination andarrange ment of parts, which will be hereinafter fully described andclaimed, and illustrated in the accompanying drawings, in which- Figure1 is a perspective View of my improved chair. Fig. 2is a verticallongitudinal sectional View of the same.

Referring to the drawings, itwill be seen that my chair is composed ofsix detachable sections-namely, the two rocker-frames 1, the rigidseat-frame or arm-section 2, the

foot-platform 3, and the two seat and back sections 4.,

Each of the rocker-frames 1 comprises the rockers 5, suitably spacedapart and provided with the vertical standards 6,/which are suitablybraced and connectedl adjacent to their upper ends by the cross-bar 7.Brackets 8 are secured to said standards and cross bar at each side ofthe frame, and upon the inner side at the upper end of each standard abracket or stud 9 is fastened.

The platform-section 3 comprises two longitudinal strips united bythefootboard 10 and provided with the upwardly-extending arms 11,`formedwith hooks 12, which en# gage the brackets 8 to support the saidfootsection.

`The receptacle or ,body of the chairis illustrated in the drawings asthe two seat and back sections mounted upon the rigid frame orlarm-section, but which may be a cradlebody, carriage, or receptacle ofany character. Theseat-frame or arm-section 2 comprises two rigid sideframes 13, formed with Varm-rests and united by the crossrods 14 and therung 23. The diagonal braces 15 of each of said side frames are formedwith notches 16,

which engage the brackets 9 upon the standards of the rocker-frames tosupport said arm-section. The outer ends of these braces 15 areconnected by the rungs 17. Each of the seat and back sections 4comprises a back 18 and a seat 19, which are pivoted together at 20. Theside rails of the back are formed with notches 21, which hook upon therungs 17 of the seat-supporting frame and support the back. Each of theside rails of the seat is formed with a series of notches 22, one ofwhich engages the rung 23 of the seat-supporting frame. The anglebetween the back and seat may be altered by varying the engagement ofthenotches 22 with the rungs 23, as will be readily understood.

In the operation of the chair when the seats are occupied the feet ofthe occupants rest upon the platform, and when pressure is exerted uponthe same motion will be imparted to the"rockerframes. These rockerframes or sections will rock in unison, owing to the manner in which vthey are connected, and the platform-section and seatframe or armsectionupon which the seats are mounted will be moved back and forth in nearlythe same plane. c at all times be level or in a horizontal position asthey arereciprocated, and the raising and lowering of the same will `bevery slight.

It will be readily seen that byfdispensing with the seat-supportingframe and the seatsections a cradle body or bed may be supported uponthe brackets 9 in the same manner in which the seat-frame is supported,and a swinging cradle may thus be produced In other words, the seatswill4 IOO 'I claim as new, and desire to secure by Letters Patent, is'-l. The combination of rocking elements, a longitudinally-movablefoot-fra1ne pivotally connected thereto, and a body disposed above thefoot-frame and pivotally connected to the said rocking elements,substantially as de-y scribed.

2. The combination of rocking elements, chair-seats, adjustablechair-backs pivotally connected to the seats, a longitudinally-movableelement adj ustably connected to the chair-seats, and a brace elementconnected to said longitudinally-movable elements, pivotally connectedto the rocking` elements, and

also pivotally connected to the chair-backs, substantially as described.

3. The combination of rocking elements, chair-seats, adjustable backstherefor, and longitudinally-movable connecting elements pivotallyconnected to the rocking elements, adj ustably connected to thechair-seats and also connected to the backs, substantially as described.

4. A chair of the character described, comprising rocker-frames, a bodyor seat frame pivotally hung upon said rocker-frames, and afoot-platform pivotally hung upon said rocker-frames below saidseat-frame, substantially as set forth. i f

5. A chair ofthe character described, comprising rocker-frames, afoot-platform pivotally hung upon said rocker-frames, a seatframe or arm-section pivotally hung upon said rocker-frames, and seat and backsections huug upon said seat-f ram e,substantially as set forth.

6. A chair of the character described, comprising rocker-frames formedwith standards having two sets of brackets, a foot-platform pivotallyhung between said rocker-frames upon one set of brackets, and aseat-supporting frame pivotally hung between said rockerframes upon theother set of brackets, substantially as set forth.

7. A chair of the character described, comprising rocker-frames formedof spaced rockers having vertical standards, each of which is providedwith an upper and lower bracket, a foot-platform formed with hook-armswhich pivotally engage the lower brackets upon said standards, and asupporting seat frame formed with notches to pivotally engage the upperbrackets upon said standards, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
